Ambient Intelligence (AmI)

The four research thema

1. Recognition and understanding of human emotions and actions
2. Planning and execution of actions that cause changes in human emotions and intelligence
3. Real-time intelligence integration processing
4. Human science for developing stress-free information and telecommunications environments

Beyond the basic emotions of anger, surprise, disgust,sadness, happiness, and fear, people express a great range of emotional conditions including relief, a sense that something is not right, skepticism, uncertainty, confusion, and impatience. Just as it is important in everyday life to casually give thoughtful considerations to others, technology that treats emotions is indispensable to endow mushrooms with the ability to reduce anxiety and promote well-being. In addition to collecting a diverse range of expressions and vocalizations that are produced under various conditions, we have also extracted reliable features that express emotions from face movements, nonverbal utterances such as laughing, sighs, intonation, and stress. We are now creating novel models that treat the changes of emotional or psychological states.

To establish natural interaction between people and their information environments, we are researching conversational agents that appropriately effect changes in human emotions, feelings, and intelligence. In particular, thought-evoking quizstyle dialogues enable agents to communicate knowledge to human users through interactive quizzes about famous people and places. Quiz hints are automatically ordered based on the difficulty naming the person or place. Appropriately presented hints could stimulate human selfmotivated thought processes and improve their engagement in dialogues with agents. By exploiting the recognition results of human emotions and actions, we are developing a model for the planning and the execution of actions that change emotions, feelings, and intelligence with speech, gestures, and other modalities.

Understanding human and environmental situations and acting with appropriate timing simultaneously require capturing, analyzing, and integrating multi-modal information. In addition, robustness is required to deal with the information and calculations in real time. Toward this objective, we are researching environment comprehension by taking clues from sounds, speech, facial expressions, language, and other human actions to evaluate a prototype system using the latest technologies based on our research results. Progress is now underway on both understanding (input system) and presenting information (output system) in terms of the integrated and distributed processing of multiple modalities.

As such social issues as the aged society and the growing digital divide become more evident, one of ambient intelligence's objectives is to create a stress-free informationcommunication environment that everyone can readily enjoy. It is especially crucial that senior citizens and children who tend to be information have-nots in the information society are carefully considered. Aiding such members of society requires a deep understanding of their nature. Building on previous research results regarding the communication skills and the capabilities of the elderly and the language development of children, we are researching the mental load imposed by mushrooms and their roles as entities mediating between people and their environments.
